Makromelt machine

By Uncategorized
This machine is designed to inject liquid synthetic, so called makromelt onto assembled cable ends.
Up to 24 moulds are mounted on a round table. A servo motor drives a piston pump which injects the hot liquid synthetic by volumetrically metering into the mould.
The water cooled moulds are easy to replace which adds to productivity and efficiency.
With this machine it is also possible to use various moulds at the same time thanks to the individually adjustable amount of makromelt volume per station. This makes cable manufacturing very efficient for cables with different types of plugs.
Above the pump is the heated repository which will refill itself automatically by the means of a suction device.
Production sequence
The desired volume of makromelt is defined on the control panel.
After pre heating, the machine starts the automatic manufacturing process.
The plugs are placed upwards into the moulds while the cable is free-hanging. Longer cables can be attached to the cable holder beneath the mould.
For the alignment of the pins a fitted counter plug is to be mounted. Hence the round table feeds the injection tool with the cable by rotation. The mould with the inserted plug is then pressed pneumatically towards the opening of the injection tool starting the moulding process automatically.
After attaining the volume the mould goes back into the starting position and the round table rotates to the next station.
The round table is designed to hold 10 or 22 stations for cooling of the injected makromelt, depending on the machine type.
When reaching the end position the finished cable is to be removed from the machine.
